Pygmy Owl (Glaucidium passerinum)
Little Tern (Sternula albifrons)
Small size diagnostic. Small head in relation to body size, and distinct short white supercilia. Slightly protruding bill. Rather dark face, with only fine white markings and stern look. Juvenile lacks finely spotted crown. Bounding, woodpecker-like flight.
Sound:Calls in a clear voice, like a straight note blown on a recorder. Each note often followed by a rhythmic, trisyllabic accent a whole tone deeper than the first note.

CCWhite forehead with white wedge above eye in all plumages. Legs, and most of bill yellow in adult breeding plumage. Very small and longwinged tern. Only 2/3 of size of Common Tern. Head and bill proportionally longer than Chlidonias species and congeners, while tail is shorter. Back paler grey and belly whiter. First primaries form a dark front edge to wing. In winter the bill darkens, legs turn a dirty yellow and the white forehead expands. Juvenile resembles adult winter, but has yellowish bill base and scale patterned back. Flight fluttering with rapid wing-beats, which together with size, is usually sufficient to determine the species.
Sound:Fairly distinct voice. Contact call a sharp "kitt", often combined to form undulating, rolling series. Not as sharp and penetrating as Common- and Arctic Tern.
